BACKGROUND Helicobacter pylori(H.pylori)infection is known to prevent the occurrence of gastroesophageal reflux disease(GERD)by inducing gastric mucosal atrophy.However,little is known about the relationship between atrophic gastritis(AG)and GERD.AIM To confirm the inverse correlation between AG and the occurrence and severity of GERD.METHODS Individuals receiving health checkups who underwent upper gastrointestinal endoscopy at Seoul National University Healthcare System Gangnam Center were included.The grade of reflux esophagitis was evaluated according to the Los Angeles classification.Endoscopic AG(EAG)was categorized into six grades.Serologic AG(SAG)was defined as pepsinogen I≤70 ng/m L and pepsinogen I/II ratio≤3.0.The association between the extent of EAG and SAG and the occurrence and severity of GERD was evaluated using multivariate logistic regression analysis.RESULTS In total,4684 individuals with GERD were compared with 21901 healthy controls.In multivariate logistic regression analysis,advanced age,male sex,body mass index>23 kg/m2,presence of metabolic syndrome,current smoking,and alcohol consumption were associated with an increased risk of GERD.Seropositivity for H.pylori immunoglobulin G antibodies was associated with a decreased risk of GERD.There was an inverse correlation between the extent of EAG and occurrence of GERD:Odds ratio(OR),1.01[95%confidence interval(CI):0.90-1.14]in C1,0.87(0.78-0.97)in C2,0.71(0.62-0.80)in C3,0.52(0.44-0.61)in O1,0.37(0.29-0.48)in O2,and 0.28(0.18-0.43)in O3.Additionally,the extent of EAG showed an inverse correlation with the severity of GERD.The presence of SAG was correlated with a reduced risk of GERD(OR=0.49,95%CI:0.28-0.87,P=0.014).CONCLUSION The extent of EAG and SAG exhibited strong inverse relationships with the occurrence and severity of GERD.AG followed by H.pylori infection may be independently protect against GERD. 相似文献

Summary Gastrointestinal complaints, including peptic ulcer, are believed to be associated and enhanced by shift work (SW). However, there are no clear reports in the literature about this acquired pathology. Serum gastrin (G) and group I pepsinogen (PG1) are thought to play a role in the pathogenesis of peptic ulcer and may be considered a useful test of the gastric function. Five adult male foundry shift workers, without any demonstrated gastrointestinal pathology, were studied over a month's span during the following weekly rotating shift schedule: 07.45–16.45, 06.00–14.00, 14.00–22.00, 22.00–06.00. Six adult, day-working males acted as controls. Blood samples drawn at the beginning and at the end of each weekly shift were assayed for G and PG1 utilizing RIA kits. Our data showed that SW causes a prominent change in the gastrin/acidopepsin secretion system. 相似文献

Summary No data are available on the localization of Pepsinogen A (PGA=PG I) and Pepsinogen C (PGC=PG II) positive cells in Barrett's epithelium. Endoscopic biopsy specimens were taken from the columnar epithelium from 23 patients (n=93), and in addition from the cardia from eight healthy control subjects (n=38). The tissue was stained by the immunoperoxidase technique with specific anti-pepsinogen antisera, and double immunostained for PGA and PGC. In the Barrett's epithelium PGA was found in 28 out of 93 biopsy specimens (30.1%) and PGC in 55 out of 93 (59.1%). Chief cells always stained both for PGA and PGC, while clear mucous cells were often PGA– and PGC+. PGA+ and PGC+ cells were found each in 100% of the biopsy specimens with fundic type epithelium, in 21.7% and 70.7% of biopsy specimens with junctional type, in 0% and 26.1% of biopsy specimens with specialized epithelium and in 12.5% and 43.5% of biopsy specimens with mixed junctional/specialized features respectively. Dysplastic epithelium stained always negatively with both anti-pepsinogen antisera. In most control cardia biopsy specimens PGA as well as PGC were demonstrable; occasionally clear mucous glands were PGA– and PGC+.It is concluded that pepsinogen-containing cells can be accurately identified in the Barrett's epithelium; their presence seems related to the histological cell type. Identification of pepsinogen positive cells may contribute to a more accurate morphological classification of the Barrett's epithelium.Presented in part at the Annual Meeting of the American Gastroenterological Association, San Francisco, May 1986 相似文献

Objective: To determine which demographic factors may influence serum gastrin and pepsinogen I (PGI) levels in duodenal ulcer patients
undergoing omeprazole treatment.
Methods: We conducted an outpatient-based prospective study in the Veterans General Hospital, Taipei, to investigate the pharmacological
effects on patients with duodenal ulcers receiving omeprazole treatment for 4 weeks. Sixty-eight patients (61 males/7 females,
aged 25–73 years) with endoscopically confirmed duodenal ulcer were included. Gastrin and pepsinogen I levels were measured
before and after treatment. Demographic factors including age, sex, smoking, ulcer healing and antral Helicobacter pylori colonization/clearance were analyzed, in order to measure their probable influences on serum gastrin and pepsinogen I levels.
Results: Ulcer healing was seen in 92.6% of patients while 48 (70.6%) antral clearances were seen in 66 H. pylori colonized patients at the end of trial. Omeprazole monotherapy led to a marked elevation of serum gastrin (85.8 pg · ml−1, SD 32.0 pg · ml−1 vs 133.9 pg · ml−1, SD 71.6 pg · ml−1, P < 0.01), and pepsinogen I (111.0 ng · ml−1, SD 36.7 ng · ml−1 vs 253.6 ng · ml−1, SD 64.8 ng · ml−1, P < 0.01) levels when measured on day 29. Only patients showing antral H. pylori clearance exhibited an influence on the magnitude of pepsinogen I elevation following omeprazole monotherapy (143.9%, SD
67.3% vs 78.6%, SD 51.2%, P < 0.01). Moreover, the sensitivity and specificity of serum pepsinogen I variations were plotted on a receiving operating
characteristic (ROC) curve. The 140% increased pepsinogen I level yielded a maximum accuracy of 80% specificity or 50% sensitivity
to predict antral H. pylori clearance.
Conclusion: Antral H. pylori clearance is at least partially responsible for the omeprzaole-induced hyperpepsinogenemia I. The magnitude of hyperpepsinogenemia
I probably provides a non-invasive alternative for predicting H. pylori clearance.

Objectives:
In Fujian Province, China, gastric cancer is one of the leading causes of mortality among all malignant tumors. Nanjing county and Minqing county are located in inland Fujian and have similar general demographics. However, the adjusted mortality rate of gastric cancer in Minqing was found to be much higher than that in Nanjing. We sought to explore factors associated with this increased risk of gastric cancer between the two counties.Methods:
We recruited 231 and 224 residents from Nanjing and Minqing, respectively, and analyzed differences between their dietary habits, Helicobacter pylori infection rates, and concentrations of serum pepsinogen I, pepsinogen II, gastrin-17, and ratio of pepsinogen I:II.Results:
Subjects in Minqing had more first-degree relatives who had been diagnosed with upper gastrointestinal tumor, more unhealthy dietary habits, a higher Helicobacter pylori positive rate, and greater proportion of abnormal serum gastrin-17 than those in Nanjing did.Conclusions:
The factors that differed between these two counties might indicate that residents in Minqing have a higher risk for developing gastric cancer than those in Nanjing do. 相似文献10.

Background: Although the association between Helicobacter pylori infection and gastric autoimmunity is now well established, to date little is known about the significance of anticanalicular autoantibodies in patients with duodenal ulcer (DU). We therefore investigated the prevalence of serum antiparietal cell autoreactivity in DU patients as well as the relationship between these autoantibodies, gastric histopathology and gastric secretory function in this setting. Methods: Forty-one consecutive patients with H. pylori-positive DU were initially recruited. In all patients, basal (BAO) and pentagastrin stimulated acid output (PAO), fasting and meal-induced serum gastrin levels, as well as serum pepsinogen I concentrations, were measured. Antral and body gastritis was evaluated according to the Sydney system. Serum anticanalicular autoreactivity was determined by the indirect immunoperoxidase technique. Results: Serum anticanalicular autoantibodies were found in 7 out of 34 patients (20%). The presence of these antibodies was associated with a significantly higher grade of body gastritis (activity: 1.9 versus 0.9) as well as with significantly higher fasting and meal stimulated gastrin levels (mean fasting gastrin, 76.4 (15.2) pg/ml versus 59.3 (20.5) pg/ml). In addition, PAO values were significantly lower in patients with gastric autoantibodies than in those without this autoreactivity (mean 0.35 (0.16) mmol kg-1 h-1 versus 0.49 (0.16) mmol kg-1 h-1). In contrast, no significant differences were found between patients with and without anticanalicular autoantibodies as regards fasting serum pepsinogen I concentrations. Conclusions: Serum anticanalicular autoantibodies can be detected in 20% of patients with DU and are associated with a more severe pattern of body gastritis, higher gastrin levels and decreased peak acid secretion values. Their presence could account for the normal or reduced acid output which can be seen in a subset of DU patients. 相似文献
